Freesia
Common Name: Freesia
Botanical Name: Freesia (leichtlinii, refracta or spp.) (FREE-zhi-a ree-FRAC-ta)
Decorative Life: 4-12 days.
Post Harvest Care:
  • Recut stems under water and place into a fresh flower food solution.
  • Do not use fluoridated water (most public water contains fluoride) as it can reduce flower development and cause leaf and flower tip burn. Using an aluminum sulfate based flower food can help reduce fluoride toxicity but cannot totally prevent it.
Harvest Instructions: Harvest when the first flower shows color. More flower buds open after harvest when the plants are grown under high light environments, where food buildup in the flowers is maximum. Depending on cultivar and growing conditions, lateral flowers on the main stems can be harvested after the main stem has been removed. Lateral flowers generally do not last as long as the main ones.
Family Roots:
  • Member of the Iridaceae (iris) family.
  • Native to South Africa.
  • Common relatives include iris, gladiolus, crocus and ixia.
Personality:
  • Flowers are funnel-shaped, 1-2 inches long, 5-8 flowers per one sided spike.
  • Stems are leafless, sometimes branched, 1-2 feet long.
  • Plant is a perennial from corms, classed as a monocotyledon, leaves mostly parallel veined.
  • Flower fragrance is variable but often intense with yellow forms.
Availability: Year-round.
Flower Color: White, yellow, red, orange or purple.
Storage Specifics: 32-36F. Wet is seemingly better than dry storage.
Tidbits:
  • Flowers in both single and double forms.
  • Name after Dr. Friedrich Freese (1785-1876), a German physician native to Keil and a student of South African plants. The specific epithet name refracta means broken.
  • Pulsing with high sugar solutions (up to 25%) can be beneficial but no such products are presently being marketed for this purpose.
  • An ethylene-induced symptom is when petals become translucent and/or fall off. Water stress can cause a surge in ethylene production, which in turn can reduce flower life.
Recent Findings: Using 'Golden Melody' and 'Moya', Burzo et al. (1995) showed that cut stem ends can emit substances into vase solutions, which in turn could be used by microbes for growth. In addition, that this problem can be greatly reduced if they are pretreated with STS. Using 'Oberon' and 'Ballerina', Amariutei et al. (1994) showed that STS treated flowers not only lasted longer than controls, but their respiration and transpiration rates were reduced and they exhibited less leakage from the cut stem ends.
Freesia
Common Name: Freesia
Botanical Name: Freesia (leichtlinii, refracta or spp.) (FREE-zhi-a)
Decorative Life: THree to five weeks, depending on interior conditions (especially light and temperature), cultivar and degree of care. They last much better at 65F or lower compared to 75F.
Post Harvest Care:
  • Keep cool and well lighted. Plants kept at 65F can last 6-9 days longer than those held at 75F.
  • Do not irrigate with fluoridated water (most public water contains fluoride) as it can reduce flower development and cause leaf and flower tip burn.
Harvest Instructions: Harvest when first floret begins to show color.
Family Roots:
  • Member of the Iridaceae (iris) family, related to iris, gladiolus, crocus and ixia.
  • Native to South Africa.
Personality:
  • Flowers are funnel-shaped, 1-2 inches long, 5-8 flowers per one sided spike.
  • Stems leafless, sometimes branched, 1-2 feet long although some dwarf cultivars exist with naturally shorter stems or branches.
  • Plant is a perennial from corms, classed as a monocotyledon, leaves mostly parallel veined.
  • While flower fragrance can be variable depending on cultivar, yellow forms can be more intense than others.
Availability: Mostly winter-spring.
Flower Color: White, yellow, red, orange and purple.
Storage Specifics: 32-36 degrees F.
Tidbits:
  • Flowers in both single and double forms.
  • Named after Dr. Friedrich Freese (1785-1876), a German physician native to Keil and a student of South African plants. The specific epithet name refracta means broken.
  • Tends to exhibit yellow leaves under interior conditions due to a wide range of factors including preharvest growing conditions and interior light and temperature levels. Possible insect problems can make this situation worse.
  • Will generally do well in light levels at least bright enough to read a newspaper in comfort but more light would be better.
  • An ethylene-induced symptom is when petals become translucent. Water stress can cause a surge in ethylene production, which in turn can reduce flower life.
